Exceptional realizations of the lorentz group: Supersymmetries and leptons

Abstract: Exceptional realizations of the Lorentz group are given via the exceptional Jordan algebra of Jordan, von Neumann and Wigner. The exceptionalSL2,C multiplets generate an intrinsically nonassociative algebra and have built in non-Abelian charge space properties. Considering these multiplets as the basis of a superspace it is shown how to give realizations of exceptional supersymmetry groups which incorporate important charge-space groups in a nontrivial way and which are different from the usual Clifford algebraic supersymmetry groups. Possible applications to the leptonic world are indicated.

The spinor superfield and Bose-fermi symmetry

Abstract: If one uses the superspace techniques of Salam and Strathdee, a new supersymmetric Lagrangian involving Dirac and Duffin-Kemmer component fields is obtained. A simple interaction Lagrangian of this spinor superfield with the scalar superfield is studied in perturbation theory, where it is shown that although the Lagrangian is not renormalizable at the 1-loop level, remarkable cancellations of divergences occur leaving only logarithmic and quadratic infinities.

Bubble graph sums in superfield theories

Abstract: The technique of superspace has led to a much better understanding of supersymmetric theories and has greatly improved the calculational methods in supersymmetric Lagrangian models.
